SPECIFICATION forming part of Letters Patent No. 643,411, dated February 13, 1900.

Application filed December 2l, 1898. Serial No. 699,903. (No model.)

To @ZZ whom t may concern:

Beit known that I, FRANK G. KAMMERER, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Means for Furnishing Pure Water; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication.

This invention relates to an improved construction in means for furnishing pure water for drinking and other purposes Where pure Water is required; and it consists in the matters hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, illustrating my invention, Figure l is a sectional view of an apparatus embodying my invention in a form adapted for domestic use. Fig. 2 is a similar view showing a modified form thereof. Fig. 3 is a similar View showing still another modification. Fig. e is a horizontal crosssection of the refrigerator, taken on line 4 4. of Fig. l. Fig. 5 is a vertical section of the stopper.

As shown in said drawings, Fig. l, A indicates a water-supply pipe which is connected with a city water-main or other source of Water-supply. A/B is a filter, having an inletpipe C, which is connected with the supplypipe A. D indicates a storage vessel or receptacle for filtered water having an outletopening in its top only. Said vessel is herein shown as having the form of a glass bottle, but may be of any suitable material or construction. Said tank or receptacle is connected with the filter by pipes E and E'. F is a depending tube which extends downwardly through the opening in the top of the vessel and is connected at its upper end with the pipe E. Said tube F and pipe F. constitute a siphon by which water may be drawn from the said vessel. G indicates a refrigerator located below the level of the storage vessel and within which is located a coolingpipe H, which is connected at one end with a pipe E2, which leads to and is connected with the pipe E and at its opposite end with a vertical pipe H', terminating in a discharge- Said refrigerator, as herein shown,

faucet I.

consists of a receptacle having double walls and adapted to contain ice, and the coolingpipe I-I is shown as having the forni of a coil located within the refrigerator. The apparatus embracing the parts referred to provides means for liltering, storing, and cooling water. Water from the supply-pipe A will enter the filter B and after passing therethrough will be delivered through the pipe E to the storage-tank D. The filtered Water may be drawn from said tankffrom the faucet I through the Siphon-tube F and pipes F. and E2, and the Water so drawn will be cooled before its discharge from the faucet by passing through the pipe H Within the refrigerator.

The drawings show anapparatus such as might be located in part in a kitchen and in part in au adjoining apartment and which is adapted for supplying filtered but not cooled water in the kitchen and water which is both filtered and cooled in the adjoining apart-A ment. In this instance the Jiilter inlet-pipe O is shown as connected with and forming a branch of a supply-pipe, which terminates in a discharge-faucet A', from which ordinary or unfiltered water may he drawn, as desired, the filter being located in the same apartment as the faucet A', which may be that used in a kitchen. Said inlet-pipe may be conven- T-fitting interposed between the end of said supply-pipe and the faucet A. The iilter shown is of a common type, consisting of a case B', provided with a removable cap or cover B2 and a porous cup B3, attached to said cover and depending Within the case, the outlet-pipe E being connected with the cover and being in communication with the interior of the cup through the medium of a hole in said cover. The pipe E is preferably attached permanently to the cover at its lower end and provided with a union or separable joint e at a point above its lower end, in order to enable the cover and porous cup to be easily removed from the lter for the purpose of cleaning said cup. The pipe E is shown as extending horizontally through the wall which separates the two apartments referred to and as connected with a vertical pipe, the portion E of which above the pipe E forms a passage for Water both toward and from the storagereceptacle. The pipe E is shown as provided iently connected with the supply-pipe by a' IOO with a faucet J, through which filtered water may be drawn from the storage-receptacle when desired, it being obvious that water drawn from either of the pipes E, El, or E? will be above or beyond the filter and will be properly filtered. Another faucet K is shown as connected by a branch pipe E5 with the pipe E' below the storage-receptacles in order to enable filtered but uncooled water to 1o be drawn from the storage-tank in the apartment in which said tank is located. It will be understood that the pipes connected with the storage vessel being always full of water the siphon formed by the upper part of the l5 pipe E and the tube F will always be in condition for operation, and water may be at any time drawn from the said vessel throughany one of the faucets I, J, or K, as desired.

The refrigerator G, shown as one convenzo ient form of such refrigerator, is made of cylindric form and is provided with a top or cover consisting of a stationary part G, which is removably attached to the body of the refrigerator, and a movable part G2, which is 2 5hinged to the stationary part tol afford access to the interior of the refrigerator and to permit the insertion of ice therein. The pipes E2 and II are shown as passing through the Vstationary part G' of the cover. The uniongo joint e', located above the said cover, is adapted to permit the lower and upper parts of said pipe to be disconnected a short distance above the said cover, so thatkwhen the lower part of the pipe is disconnected from the upper 3 5 one the stationary part G of the cover may be removed from the body of the refrigerator, with the cooling pipe H attached thereto. Such removal of the vcooling-pipe will be occasionally desirable or necessary to permit 4o the thorough cleansing of the interior of the refrigerator. The refrigerator will preferably be provided with an outlet-pipe L, provided with a faucet M, through which Water accumulating from the melted ice may be drawn from the refrigerator when required.

5o merged in the cold water and beneath the ice,

aiords ythe principal means of cooling the water passing through the coil.

The orice of the storage vessel D when the same is made of glass in the form of a bottle,

5 5 as shown, will preferably be closed by a stopper or cork Cl, through which the siphon-tube F is inserted. N is an overiiow-pipe, the upper end of which communicates with the vessel through a passage in the stopper CZ 'and 6o the lower end of which may lead to any place suitable for the disposal of overow-water. Conveniently the lower end of the said overflow-pipe may pass through the cover G of the refrigerator and discharge therein. The

overflow-pipe will be needed only to prevent excessive pressure on the storage vessel should the filter be left in operation until the storage vessel is completely filled, it being obvious thatin the absence of an overtiowpipe the vessel would under these circumstances be subjected to the full pressure of the city main. The storage vessel may, however, if desired, be so constructed as to withstand the full pressure of the water-supply system in connection with which it is used, in which case any overflow-pipe will be unnecessary.

In Fig. 2 is shown a water-supply apparatus, which is identical in all respects with that shown in Fig. l, with the exception that in place of the filter B (before described) in this instance a still or distilling device O is employed to supply water to the-storage vessel. Said still, as shown, consists of a water vessel P, having a depending tubular leg P', a condensing and discharge tube Q, which passes-through said leg and has an open upper end located within the vessel P above the water-line therein, and an annular gas-burner R, located beneath the main `part of the said vessel. A water-supply pipe S is connected with the bottom of the water-leg-P, and an overlioW-pipe is connected with the side of the vessel P. The discharge-tube Q enters the storage vessel th rough the stopper or cork therein. Obviously any other form of distilling apparatus may be employed for supplying the water to the storage vessel instead of that herein shown.

In Fig. 3 I have shown an apparatus in which is combined the features illustrated in Figs. 1 and 2that is to say, it contains the filter illustrated in said Fig. 1 and also the distilling apparatus shown in Fig. 2. The parts illust-rated in this instance are constructed in the same manner-as shown in said Figs. 1 and 2 and are lettered the same in the drawings, except that in this instance a pipe S leads from the outlet-opening of the filter to the leg P' of the distilling apparatus, by which water is delivered directly from the filter `to the distilling apparatus.

As a further and separate improvement I have provided a closure for` the storage vessel of a form adaptedfor the convenient connection of the siphon-tube and overflow-pipe with said storage vessel, such inclosure being adapted for use not only in connection IOO with the special apparatus herein shown, but

in other cases where it may be desired to connect a Siphon-tube andan overflow-pipe with a similar vessel. Said inclosure embraces in connection with the cork or stopper d a metal cap D', of tubular form, which 'forms an annular chamber above the stopper proper, which chamber communicates with a central opening inthe stopper which is larger than the siphon tube that passes therethrough,and said cap is provided with a like projecting tube d with which the overflowpipe is connected. Said cap is also provided above said overliow-pipe with a packingring D2, which surrounds the Siphon-tube and forms a tight joint between the same and mit the convenient insertion and removal ofM the Siphon-tube and to insure a tight joint between the saine and the stopper while at the same time affording free communication between the interior of the storage vessel and the overflow-pipe.

As a convenient construction in the closure the cap proper has attached to it a depending tube D3, which passes through the cork or stopper CZ and has a flange at its lower end adapted to hold the stopper firmly in place upon the cap. The top of the said cap is moreover provided with an inwardlyextending fiange which extends over the packing-ring and serves to confine the saine in place.

In some cases it may be desirable to secure the closure firmly in the mouth of the vessel--as, for instance, when thek same is subject to considerable internal pressure I provide in connection with the cap referred to a device by which it may be secured to the neck of the vessel when said neck is provided with a fiange like that of an ordinary bottle. This holding device may be of any suitable form; but preferably and as an advantageous construction I provide the said cap with a depending fiange D4, which surrounds an upper part of the neck of the vessel and projects slightly below the shoulder thereon, so that it may be bent inwardly to confine the cap upon the neck of the vessel. This provision for securing the cap or closure in the mouth of the vessel may be desirable, even when the vessel is subject to no special pressure from the inside, in order to securely hold the said closure and the pipes connected therewith in place and prevent their disconnection or dislodgment in the usual service or use of the apparatus.

I claim as my inventionl. The combination with a refrigerator, of a storage vessel located above the refrigerator and having an opening in its top only, a water inlet and exit pipe connected with the storage vessel by a siphon, a water-supply pipe connected with said inlet and exit pipe, a discharge-pipe also connected with said inlet and exit pipe and leading downwardly from said storage vessel, an overflow-pipe connected with the top of the storage vessel, and a coolin g-pi pe Within the refrigerator connected with the lower end of the dischargepipe and terminating in a discharge-faucet.

The combination ofa refrigerator, astorage vessel located above the level of the said refrigerator and provided with an opening in its top only, a Water-lter, a pipe supplying Water to 'said filter under pressure, a discharge-pipe connected with the storage vessel by a Siphon and leading to the refrigerator, a pipe leading from the discharge-opening of the filter to the said discharge-pipe and through which water is delivered to said pipe and to the storage vessel through the pressure of the water in the supply-pipe, and a cooling-pipe in the refrigerator connected with the said discharge-pipe and terminating in-a faucet.

4. The combination of a Water-filter, a pipe supplying Water thereto under pressure, a storage vessel, an inlet and exit pipe connected with said storage vessel, a pipe leading from the filter to said inlet and exit pipe through which water is delivered to the storage vessel th rough the pressure in the supplypipe, a discharge-pipe connected with said inlet and eXit pipe and through which Water from astorage vessel is discharged by gravity, said discharge-pipe being provided with a faucet, and an overflow-pipe leading from the top of said storage vessel.

' 5. The combination of arefrigerator, astoragevessel located above the level of said refrigerator and provided with an opening in its top only, a Water-filter, a pipe supplying Water to said filter under pressure, a distilling apparatus into which water is discharged from the filter by pressure Within the supply-pipe, the said distilling apparatus. being located above the storage vessel and discharging into the same by gravity, a discharge-pipe connected with the storage vessel by a siphon and leading to the refrigerator, a cooling-pipe in the refrigerator connected with the dischargepipe from the storage vessel and terminating in a faucet, and an overoW-pipe connected with the top of the storage vessel.
